BUCK-SAW FRAME.

SPEOIFIGATI ON forming part of Letters Patent No. 281,837, dated July 24, 1883.

Application filed May 1, 1883. (ModeL) To all whom, it may concern.-

Be it known that I, WILLIAM OLEMsoN, of Middletown, Orange county, NeW'York, have invented a new and useful Improvement in BuckSaw Frames, of which the following is a full, clear, and exact description.

piece I), and the tie-rod c are all of ordinary.

construction, and the sawblade e is secured at its ends in the side pieces, cu, in the ordinary manner. 7

d d represent the braces of the frame, which reach from about the center of the length of the crosspiece b diagonally up to the upper ends of the side pieces, a a. At the lower ends the braces d d are held in place upon the cross-piece b by means of the staple f, or other suitable fastener. At their upper ends they are held in place by the tie-rod 0, passing through suitable holes made in their upper ends, as will be understood from the drawing, and at theirupper and lower ends they are beveled to fit upon the cross-piece and against the side pieces, and at their lower ends the braces abut against, each other, to prevent any sliding movement upon the cross-piece b when the nut g is turned for straining up the frame.

The action of the frame is as follows Upon the screw 9 being turned the upper ends. of

the side pieces will approach each other against the, action of the braces d d, which will depress the cross-piece b in the center, which depression of the cross piece permits the upper ends of the side pieces being drawn closer together than they would be if the said crosspiece remained straight, and consequently the straining of the saw-blade to greater extent, and the frame, as a whole, at the same time braced and made more rigid and firm than by any system of bracing known to me. Besides, the frame, as a'whole, is cheap, durable, and not liable to get out of order.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a buck-saw frame, the combination, with the side pieces, a, and central straight crosspieoe, b, of the straight diagonal bracesd, having beveled ends, and secured to the center of the cross-piece, with their ends abutting, by the staple f and the rod a passing through the ends of the braces at, substantially as shown and described.
